Encapsulating a crawl space is a common way to deal with moisture or flooding. It is also an easy way to quickly get control of the air quality in the home and lockout rodents and insects. When you’re thinking about “green-ovating” your home, or simply getting control of the moisture or humidity, when you have a crawl space, you must encapsulate.
Encapsulation does a great deal for the crawlspace and for the home above.
What the process is and what it does
The practice of encapsulating or “sealing off” a crawlspace is done to lock out moisture and cut off the connection between moisture, water and the joists of a home. By running a vapor barrier down the walls of a crawl space to completely cover the floor, you essential separate the outside from the inside of the home.
This vapor barrier will be the flexible membrane between the walls and floor and the rest of the home. A properly designed vapor barrier will limit the transfer of moisture through it while regulating the speed at which air will naturally pass through. This helps to limit and control the amount of moisture that will find its way into the air space and completely segregate liquid water and direct it to a sump location.
5 helpful tips when having a Vapor Barrier installed in your crawlspace:
1.) Not all vapor barriers are made for this task – careful. There are many products out in the world that claim to be able to fully encapsulate a crawl space. Make sure that your vapor barrier has a low “perm” rate and that it is at least 14mil thick. If you’re planning to use the space for storage make sure that a flexible sub-flooring product is also placed on top of the vapor barrier to protect it.
2.) Cover the walls too – all too often contractors forget to also encapsulate the walls of the crawl space when installing a vapor barrier. This can still allow water and moisture into the basement and therefore render the whole project useless. Take care to make sure it’s installed properly.
3.) Don’t use sprays. – Sealants and sprays aren’t designed to be applied on the interior of the basement. They are good in many circumstances as the “first line of defense” but as the last, they can’t hold the pressure and moisture trapped in a wall.
4.) Install a sump and a dehumidifier – to totally control the moisture level in the crawl space it’s imperative that you have a sump pump and a dehumidifier installed. Moisture will still exist, although not to dangerous levels, but a sump will remove any liquid water your encapsulation traps, and the dehumidifier will deal with any residual moisture that naturally collects in the space.
5 Helpful Tips For When it is Time to Encapsulate Your Crawl Space
I recently came across a Consumer Reports article that served as a good reminder to homeowners about some of the home's maintenance issues that are just too important to put off. With today's economy, it is easier to justify holding off on repairing a leaking basement wall crack because it seemingly does not pose an immediate threat, outside of a little inconvenience, of course.
Problems related to the foundation's structural stability or the indoor air quality of the home requires more immediate action; such issues are essentially putting the health and overall safety of the family at risk: not tomorrow, or a year from now, but at this moment.
While bad news for the homeowner, such problems are good for basement waterproofing and foundation repair contractors - the need for their services will always exist. The Consumer Reports article lists a couple of problem issues that the homeowner should be concerned about - the growth of mold and mildew and the formation of cracks in poured foundations. As a business owner who works with the basement waterproofing industry, these are two areas of concern that I am well familiar with.
The growth of mold and mildew can occur inside a home for endless reasons. The most prominent areas are basements and crawl spaces, where excess moisture is a sure bet unless the necessary measures are taken. Concrete walls are prone to the seepage of water vapor - leaking water from cracks in the foundation or the floor adds to the problem. The basement and crawl space provides the ideal environment for trapped moisture to eventually grow into mold spores and mildew.
Concrete cracks in poured foundation walls usually occur as a result of shrinkage or settling around the foundation. Cracks forming as a result of shrinkage in the concrete typically do not pose a structural threat, yet they may cause headaches for the homeowner the second they begin to leak water.
Whether such foundation cracks are structural or not, it is best not to leave them exposed for long, as it relates to the concern of the home's indoor air quality. These cracks, as well as in concrete floors, may provide an opening for soil gases. The infiltration of soil gases, in addition to the growth of mold and mildew can be enough to create an indoor air quality nightmare. The bad air circulating inside the basement and crawl space affects the entire home - 50% of the air circulating throughout the home originates from the home's lowest level.
Concrete cracking is unavoidable. Properly addressing them early on will minimize further problems down the road. Further indoor air quality concerns may also be addressed by implementing the proper waterproofing and sealing techniques throughout the basement and crawl space. There are plenty of qualified contractors throughout the United States and Canada available to service such jobs.
It's reassuring to know that our message is backed up by an objective source such as the Consumer Reports. You view the article at the provided link, http://shopping.yahoo.com/articles/yshoppingarticles/418/5-home-repairs-not-to-ignore/.
You can't put a price on the long-term stability of the home and health of the family.
Addressing Moisture, Mold and Radon Gas in Basements and Crawl Spaces With Application of a Deep-Pen
Owning a home with a basement can give us additional living space that is not typically available in a home with a crawl space. Many people put recreational rooms in the basement as well as using them for storage and often as a personal workshop. It may be difficult, however, whenever water in the basement becomes a problem. There are really two different ways in which water can invade this area of our home, both of which will take some form of waterproofing to correct. They can either come in slowly, almost undetected by us or it can quickly invade our basement and cause it to be flooded.
Since the basement is below ground level, moisture is often a problem, even if it is not visible. It may show up as mold or mildew that begins to appear on the walls and although you cannot actually see the moisture that is present, there are plenty of telltale signs that will help to identify the fact that you have a problem.
Doing a little bit of basement waterproofing for this usually means putting a specific type of paint on the walls or perhaps even spraying them down with chemicals so that they are impervious to mold growth. It may also help if you run a basement dehumidifier on a regular basis, even after you have completed the basement waterproofing project.
The other way that water can invade our basement is all at one time which can cause it to be flooded. I have personally had a difficulty with this for many years and it can be destructive, especially if you use the basement for living space or storage. If the water is coming in at one specific location, sealing that location in some way or another may help to cure the problem a little bit.
There may be times, however, whenever more drastic measures need to be taken. If you're basement floods on a regular basis, you may need to dig down to the bottom of your foundation on the outside of the walls and install a French drain. This will divert any water away from the house so that it does not end up in your basement.
Having a problem with water in your basement is simply keeping you from enjoying part of your house. Although waterproofing your basement is going to take a little bit of work, it will all be well worth the effort whenever you can take this part of your home back again.
